I'm voting Big Nog although my vote goes out to both of the twins.Simply put, you will NOT stop a Nogueira. You may beat them by decision, but they are never ever going to give up and they are never ever going to get knocked out. I've seen the both of them take unbelievable amounts of punishment and just keep going. Sakuraba would be next on my list.

My vote goes to Randy, also a bit biased on my part. Beating the two best light heavyweights in the ufc at the time one after the other at 40 years old is legend material. Royce has to be up there to, never submitted and fought Sakuraba for 90 minutes.

I went with Sakuraba(What can I say? I'm also biased, as Saku is one of my all time favorites). The guy took manly asskickings from Arona & Silva, and didn't quit. He was slammed(Hard, I might add) repeatedly by Rampage, and didn't quit.

Big Nog is a good choice as well. This guy took beatings from Fedor, and didn't quit. A lesser man would've quit, but Nog is just tough as hell. Both Nog's are tough, but Big Nog was getting blasted by Cro Cop & Fedor, and just didn't say "Ok, I give up". Strong chin, and just unbelievable willpower. I don't even think a shotgun would stop either Nogueira brother. Big Nog faced Bob Sapp, took a Ganso Bomb from Sapp, and still went on to armbar him.

Here's one guy who often gets overlooked: Takayama. This guy took 3 manly asskickings from guys who were way better than him. Fujita gave him a long, sickening beating. Frye just tore through the guy, and really made his face look alien-like....well, an alien who was just shot in the face. Schilt gave him another sickening beatdown. Takayama didn't quit, and he showed more heart in the Frye fight, than pretty much anyone not counting Big Nog that year.

i went with sakuraba based on the reason's damone has already mentioned. the dude doesn't quit. he has taken some assbeatings in his career but the guy keeps coming and never gives up on a fight. he's got a big heart. and nog isn't too far behind. his fights with fedor and mirko proved how much heart he really has.

Saku because of the slams he took from Rampage going for submissions, yet he never quit trying to lock them in(his back had to be hurting). Yoshida because of his fight with Crocop, I was begging for him to stay down a couple times, but he kept getting up and taking another leg kick until he couldn't even stand any longer.
